But tomatoes are different in size, so each tomato contains different special protein. The success of traditional vaccination depends on whether everyone receives the same vaccine dose every time. If the dose is too much, it will produce some adverse reactions; Too little may have no effect. Therefore, people can't help asking: Is it dangerous to eat a big tomato? How much is appropriate to eat? In this regard, researcher Liu explained: "Traditional vaccination needs to control the dose, but genetically modified tomatoes should not consider this issue. Because the transgenic tomatoes that prevent hepatitis B are absorbed by the digestive tract and produce antibodies in the human body, they have immune ability. If the tomatoes you eat are too large, the extra vaccine ingredients will be excreted automatically, and there will be no side effects on the human body. In addition, genetically modified foods must undergo strict safety testing before they go on the market. We have finished the animal test and are now conducting the safety test. I and other researchers in the institute have eaten genetically modified potatoes and tomatoes, and we are in good health now! "
Researcher Liu also introduced that the listing of genetically modified tomatoes that can prevent hepatitis B should go through four stages: intermediate test stage, environmental release stage, production test stage and production certificate declaration stage.
